Control bits inhibit portions of the cache memory from being accessed. ... 09/28/06 - 20060218354 - Global modified indicator to reduce power consumption on cache miss A processor includes a cache memory having at least one entry managed according to a copy-back algorithm. A global modified indicator (GMI) indicates whether any copy-back entry in the cache contains modified data. On a cache miss, if the GMI indicates that no copy-back entry in the cache contains modified ... 08/17/06 - 20060184745 - Organization of dirty bits for a write-back cache A cache system is constructed in accordance with an architecture that comprises a tag array into which tags are stored that are used to determine whether a hit or a miss into the cache system has occurred. Further, the cache system comprises a data array into which cache lines of ... 08/10/06 - 20060179250 - Data processing system and method for efficient l3 cache directory management A system and method for cache management in a data processing system having a memory hierarchy of upper memory and lower memory cache. A lower memory cache controller accesses a coherency state table to determine replacement policies of coherency states for cache lines present in the lower memory cache when ... 06/29/06 - 20060143407 - Methods and structure for improved storage system performance with write-back caching for disk drives Methods and associated structures for utilizing write-back cache management modes for local cache memory of disk drives coupled to a storage controller while maintaining data integrity of the data transferred to the local cache memories of affected disk drives. In one aspect hereof, a state machine model of managing cache ... 06/29/06 - 20060143406 - Predictive early write-back of owned cache blocks in a shared memory computer system A method for predicting early write back of owned cache blocks in a shared memory computer system. This invention enables the system to predict which written blocks may be more likely to be requested by another CPU and the owning CPU will write those blocks back to memory as soon ... 06/22/06 - 20060136675 - Method of storing data in blocks per operation The present invention is to provide a method of storing data for driving an MMC or SD under an operating system (e.g., Linux), which comprises the steps of collecting data in a plurality of discreet blocks of a high-speed buffer for each writing request made by a device driver under ... 06/08/06 - 20060123200 - Storage system, and control method and program thereof A cache processing unit manages the data, which is in a cache memory, in a page unit including plurality pieces of block data each of which serves as an access unit of a host, and processes input and output requests from a host to a storage device. In a case ... 05/25/06 - 20060112236 - Method and apparatus for dma-generated memory write-back A method for memory write-back provides a memory access controller and then generates a write-back pattern in the memory access controller. The write-back pattern is then written back into a memory starting at a predetermined address location and continuing for a predetermined length of the addressing space of the memory. ... 05/18/06 - 20060106993 - Mechanism for handling explicit writeback in a cache coherent multi-node architecture A method and apparatus for a mechanism for handling explicit writeback in a cache coherent multi-node architecture is described. In one embodiment, the invention is a method. The method includes receiving a read request relating to a first line of data in a coherent memory system. The method further includes ... 04/27/06 - 20060090040 - Techniques to improve cache performance Method and apparatus to improve cache performance using interarrival times between demand requests are described. ... 03/09/06 - 20060053257 - Resolving multi-core shared cache access conflicts Preventing request conflicts within microprocessors and/or computer systems. More particularly, embodiments of the invention relate to a technique to manage request conflicts within a processor and/or computer system in which a number of accesses may be made to a particular cache or group of caches shared amongst a set of ... 01/19/06 - 20060015689 - Implementation and management of moveable buffers in cache system The present invention provides parallel processing of write-back and reload operations in a cache system and optimum circuit utilisation by implementing moveable buffers in a cache storage. However, the data and associated pointers are not permanently assigned to a particular buffer—hence, the buffers can move logically around in the facility. ... 12/08/05 - 20050273563 - System and method for canceling write back operation during simultaneous snoop push or snoop kill operation in write back caches A cache write back operation, write back modified data to memory from cache data array to fix inconsistency between them can be cancelled by the results of a comparison of the progress between a write back and snoop push or snoop kill operation. Write back is intended to make an ... 09/15/05 - 20050204099 - Method and apparatus to write back data Briefly, in accordance with an embodiment of the invention, a method and apparatus to write back data is provided. The method may include setting a status corresponding to a block of data in response to a change in address mapping to indicate that the block of data is pending write ... 07/21/05 - 20050160233 - System and method to facilitate ordering point migration to memory A system may comprise a first node that includes an ordering point for data, the first node being operative to employ a write-back transaction associated with writing the data back to memory. The first node broadcasts a write-back message to at least one other node in the system in response ... 06/30/05 - 20050144396 - Coalescing disk write back requests Cache write back requests may be coalesced to reduce disk accesses and improve overall system performance in some embodiments of the present invention. Contiguous and non-contiguous data from more than one cache line may be coalesced into a single write back request and written back in one atomic write to ... 06/23/05 - 20050138297 - Register file cache Embodiments of the present invention relate to a system and method for associating a register file cache with a register file in a computer processor. ... ### FreshPatents.com Support |
